Regulatory structures in Sefidroud irrigation network Broad Crested Weir   side weirs are structures for regulating and diverting excess flows in hydraulic engineering. These types of structures are built next to canals, canals and rivers in order to contain the flood and reduce its risks by diverting and overflowing part of the flood flow whose water level in the main canal or waterway has increased from a certain heightbe at the bottom .   Lateral overflows are hydraulic structures that are used to divert flow in irrigation and drainage systems. In the current situation, one of the important factors in the high efficiency of distribution networks and the satisfaction of farmers is the optimal performance of water catchment structures. Therefore, in order to make a fair distribution throughout the network, we must first find out about the correct and principled operation of water catchments, and if there is a problem in the water catchments, we should fix it.   The regulated water flow from the #Sefidroud_Dam is distributed through the Tarik diversion dam, the water tunnel on Foman, the Goleroud diversion dam and the Sangar diversion dam, the Goleroud canals and the right and left Sangar canals and hundreds of kilometers of main and secondary channels within the scope of the #Sefidroud_irrigation_network . It nourishes the paddy fields. Sefidroud dam is the largest reservoir dam in Gilan province in Iran, which is built on Sefidroud river and downstream of the confluence of 2 Qezal Ozan and Shahroud rivers, 75 km south of Rasht city and adjacent to Manjil city.   Gilan province is considered to be the largest producer of local and high-quality rice varieties in Iran, which ranks first in the country in terms of cultivated area and second in rice production.

The Special Investment Facilitation Council (SIFC) has requested the Water Resources Ministry to present a proposal for a crop-specific Abyana (water pricing) plan to cover the operations and maintenance (O&M) costs of canals and irrigation systems, while also promoting water conservation. Additionally, the four federating units have been urged to contribute funds from the revenue collected through water pricing for national water projects, including dam constructions. The SIFC Secretariat has confirmed that the Water Resources secretary has been asked to develop an irrigation water pricing mechanism, incorporating suggestions from the chief secretaries of the four provinces. According to estimations provided by senior ministry officials, the implementation of a rational pricing mechanism could potentially generate revenue of around Rs300-325 billion. These funds could be instrumental in the upkeep and enhancement of respective irrigation systems, as well as the financing of future national water projects, notably dams. Previously, the Water Resources ministry had proposed a plan suggesting the implementation of a rational water pricing mechanism by provincial governments. This initiative aims to facilitate the improvement of irrigation systems at the provincial level, including the canal lining for ensuring the equitable provision of water to all farmers, along with contributing to national water projects and dam constructions. To explore and analyze the water pricing mechanism in Pakistan, the Water Resources ministry sought the assistance of the World Bank and approached the Economic Affairs Division (EAD) for engagement with the international financial institution. The comprehensive plan has been devised in response to the financial constraints faced by the federal government, posing challenges for adequate funding allocation in critical sectors such as healthcare, education, transportation, and housing. With the current average water pricing ranging from Rs125 to Rs200 per acre annually, the potential revenue could significantly increase if the minimum suggested fee of $25 (approximately Rs7,000) per acre annually is implemented, given the substantial agricultural land area in Pakistan. #SIFC #Irrigation #Revenue #Pakistan #Mechanism

Credit to Jed Macapagal June 17, 2024 Water supply from Cavite dams to be tapped for household use https://lnkd.in/g9n5XQr2 RIGHTS for the use of dams in Cavite originally intended for irrigation of the National Irrigation Administration (NIA) will be auctioned off to be utilized for domestic use, the Department of Environment and Natural Resources (DENR) said. DAVID DENR Undersecretary Carlos Primo David said there are 22 dams in Cavite being managed and maintained by NIA even if there are no longer existing farms to serve. There are not much farms in Cavite nowadays as they were converted to households. NIA will turn over these dams to the provincial government of Cavite which will conduct the auction. David who also heads the Water Resource Management Office (WRMO), said out of the 22 dams, four have been tapped by Maynilad, 13 are transferred to be managed by the provincial government of Cavite and the remaining five are also set to be transferred for the local government. Cavite has existing supply of ground water and some surface water but it will no longer suffice. At present, our initial target is to provide additional water for one million people in Cavite. Since the management of NIA’s dams were transferred to the province of Cavite, hopefully sometime in October they will have it bidded out. Ronald Padua, Maynilad water supply operations head, said out of the four dams secured by the company for water supply in Cavite, two are in Bacoor and the other two are in Imus. ● Padua said one of the dams, Anabu Dam, has been operational since late last year providing 4 million liters per day (MLD) to 8 MLD in Imus. ● Padua said a second dam in Imus is scheduled to be operational by the third quarter through the Julian modular treatment plant with a 4 MLD capacity. ● Maynilad said there is also an ongoing construction for the Molito Dam in Molino that is scheduled for completion by early or mid-next year. ● Padua said the fourth Ligas Dam is currently awaiting for an official award of its contract which is still completing its permits. If awarded this year, the Ligas Dam will be completed and operational by end-2025 or early 2026 since it will have a significant 18 MLD capacity.

No lift for low dam levels: DAM levels across the country remain substantially lower than a year ago, with most water reservoirs not receiving substantial inflows yet during the current rainy season. According to the Namibia Water Corporation’s latest update on the state of the country’s dams, the three dams on which Windhoek depends for a major part of its water supply – Swakoppoort, Von Bach and Omatako – are currently holding about 30,3 million cubic metres of water, compared to combined contents of 63,3 million cubic metres a year ago. The three dams are currently filled to 19,6% of their combined storage capacity – less than half of their combined level of 41% a year ago. The Hardap Dam near Mariental, which is an important source of water for irrigation, is currently storing about 35,8 million cubic metres of water, which is 12,2% of its capacity, compared to a level of about 41,6% (122,8 million cubic metres) at the same time last year. The Naute Dam near Keetmanshoop, which also stores water for irrigation purposes, holds about 33,2 million cubic metres of water at the moment, compared to 56,6 million cubic metres a year ago. The main dam levels reported by NamWater yesterday, with the dams’ readings at the corresponding time a year ago in brackets, are: Swakoppoort 39% (76,4%) Von Bach 11% (28,7%) Omatako 0,7% (2,6%) Hardap 12,2% (41,6%) Neckartal 83,7% (93,5%) Naute 39,8% (67,8%) Oanob 42,7% (62,5%) Otjivero Main 4,6% (14,7%) Otjivero Silt 1,9 (0,7%) Tilda Viljoen 5% (40%) Daan Viljoen 5,5% (16%) Olushandja 37,4% (18,3%) Friedenau 55,4% (72,6%).

Drainage problems and loss of yield may be as a result of over-irrigation, shallow soils or low-quality water and/or salts. If economically justifiable, artificial drainage may be considered, or irrigation should be withdrawn from the specific field. Salinity problems encountered in irrigated agriculture are very frequently associated with an uncontrolled water table within one to two meters of the ground surface. In most soils with a shallow water table, water rises into the active root zone by capillarity and, if the water table contains salts, it becomes a continual source of salts to the root zone as water is used by the crop or evaporates at the soil surface. Salinization from this source can be rapid in irrigated areas in hot climates where portions of the land remain fallow for extended periods. The rate of soil salinity accumulation from an uncontrolled shallow water table will depend upon irrigation management, salt concentration and depth of the groundwater, soil type, and climatic conditions (FAO, 1995). https://lnkd.in/d_YTVX6K

June 20, 2024   Dinuba – On Friday, June 21st, Alta Irrigation District starts a new entitlement schedule. Over the course of a water run, the District adjusts the entitlement schedule to match the available supply. According to information from the Kings River Water Association (“KRWA”) and the California Department of Water Resources (“DWR”), Kings River runoff is anticipated to be in a “normal” range for this water year (October 1st to September 30th). Keeping with typical operations during a “normal” runoff condition, water allotments will be available to land with an entitlement category greater than or equal to 25%. Land with a 5% entitlement classification (aka “Groundwater Only”) will not receive an allotment for the remainder of this year’s water run. Below is the allotment schedule for the new 14-day irrigation cycle. https://lnkd.in/gTzN2XtA

Farmers under summer stress: When irrigation turns into dewatering Something unexpected is happening in agriculture: Where normally the irrigation systems run hot in the scorching summer heat to keep the drying greenery alive, this year it is the dewatering pumps that are giving farmers sleepless nights. Instead of laboriously irrigating the fields, they are now struggling with a flood that one would have expected in April - and not at a time when the sun is normally blazing mercilessly from the sky. The reason for this strange scenario is the incessant rainfall, which has turned the land into a veritable swamp. The fields look more like rice paddies than wheat fields. The modern farmer of today, otherwise a master of water management, is suddenly faced with the challenge of getting the flooding under control - in the middle of summer! This is where the heroes of the hour come into play: Hüdig Celle dewatering pumps. Originally intended to protect construction sites or cellars from water, they are now finding a new purpose in the fields. The devices are operated at high performance to get the water out of the fields before the next rain shower ruins everything again.
