“…This extensive irrigation network consists of ∼2100 km of irrigation ditches and drains which flood-irrigate ∼25 000 ha of cropland. 41 On average, agricultural drains return water to the mainstem Rio Grande ∼50 km downstream of where water was diverted from the river. During the nongrowing season (November−February) there are no significant withdrawals for irrigation, with water released from Cochiti Reservoir flowing unimpeded to Elephant Butte Reservoir.…”

Closing nutrient loops in terrestrial and aquatic ecosystems is integral to achieve resource security in the food-energy-water (FEW) nexus. We performed multiyear (2005-2008), monthly sampling of instream dissolved inorganic nutrient concentrations (NH4-N, NO3-N, soluble reactive phosphorus-SRP) along a ∼ 300-km arid-land river (Rio Grande, NM) and generated nutrient budgets to investigate how the net source/sink behavior of wastewater and irrigated agriculture can be holistically managed to improve water quality and close nutrient loops. Treated wastewater on average contributed over 90% of the instream dissolved inorganic nutrients (101 kg/day NH4-N, 1097 kg/day NO3-N, 656 kg/day SRP). During growing seasons, the irrigation network downstream of wastewater outfalls retained on average 37% of NO3-N and 45% of SRP inputs, with maximum retention exceeding 60% and 80% of NO3-N and SRP inputs, respectively. Accurate quantification of NH4-N retention was hindered by low loading and high variability. Nutrient retention in the irrigation network and instream processes together limited downstream export during growing seasons, with total retention of 33-99% of NO3-N inputs and 45-99% of SRP inputs. From our synoptic analysis, we identify trade-offs associated with wastewater reuse for agriculture within the scope of the FEW nexus and propose strategies for closing nutrient loops in arid-land rivers.

“…The flow of water with head less than 5 m can be found on irrigation channels. The flow of water in irrigation canals that have very low head can be utilized to generate electricity [3][4][5][6]. To utilize a water flow with very low head, such as in an irrigation stream, the Dethridge wheel, which originally used as a flow measurement, is used for electricity generation with an efficiency of 60% [7] and its performance improves in the channel width that is two to three times greater than the wheel width [8].…”

Utilization of low head flow water has long been used to generate power by using water wheels and low head turbines. Dethridge wheel which is usually used as a tool to measure the flow of water has also been studied its potential to become hydro power generation. Therefore, this study aims to compare performance between overshot Dethridge wheel and undershot Dethridge wheel. For this purpose, a small scale channel for the operation of a water wheel is equipped with a digital flow meter, a pump that has a debit of up to 25 l/s, a pony brake for a torque meter, and an inverter to adjust the flow rate by changing the pump rotation. The research was conducted at Laboratory of Mechanical Engineering, UHAMKA in Jakarta, Indonesia. Flow rates vary from 5 to 11 l/s with head of 10 cm and 537 cm. The efficiency of undershot and overshot, at the peak, are 21% and 18%, respectively.
