“…The location and storage capacity of structures constructed during different periods were recorded through a topography survey. The elevation of the landscape was measured through a “total station” survey instrument and a contour map developed, based on which the water harvesting capacity was measured through Simpson's rule (Biswadeep 2015; Takal et al 2017). Runoff at one of the micro‐watersheds was measured using an automatic gauge recorder between 2002 and 2006 (Figure 1).…”

Agricultural water management (AWM) interventions play an important role in ensuring sustainable food production and mitigating climate risks. This study was carried out in a watershed located in a low rainfall (400-600 mm) region of western India. The Soil and Water Assessment Tool model was calibrated using surface runoff, soil loss, and reservoir storage levels, between the year 2000 and 2006. The investigation indicated that the various AWM interventions increased groundwater recharge from 30 mm/year to 80 mm/year and reduced surface runoff from 250 mm/year to 100 mm/year. The intervention structures were refilled two to three times during the monsoon season depending on rainfall intensity and duration. The interventions have the advantage of building a resilient system by enhancing groundwater availability even in dry years, stimulating crop intensification and protecting the landscape from severe erosion. The results indicate that soil erosion has been reduced by more than 75% compared to the nonintervention situation. Moreover, the AWM interventions led to the cultivation of 100-150 ha of fallow land with high-value crops (horticulture, vegetables, and fodder). Household income increased by several folds compared to the nonintervention situation. The study showed about 50% reduction in downstream water availability, which could be a major concern. However, there are a number of ecosystem trade-offs such as improved base flow to the stream and reduction in soil loss that should be considered. The study is of great importance to stakeholders to decide on the optimal design for AWM interventions to achieve sustainable development goals.

Even though the management operation guidelines have been determined, the optimal management of the Citarum Cascade Reservoir has not yet been achieved. Optimal management of cascade reservoirs in an integrated manner is difficult to be carried out due to complex operating procedures and high uncertainty of hydrological components. So, research on the optimal management of each reservoir considering the discharge forecasting model as input discharge (Qin) was proposed. The objective of this study was to optimize Cirata Reservoir’s operational management. Hence all raw water demands are met without any water wasted through the spillway, as indicated by the correlation between inflow discharge (historical and model) and the correlation between trajectory (guideline and actual). In this case, discharge forecasting methods used were Discrete Markov and ARIMA. The continuous with five years return period (R5 continuous), continuous with ten years return period (R10 continuous), 3-classes Discrete Markov, and 5-classes Discrete Markov methods were applied for guideline trajectories. Based on the results, the correlation coefficients between inflow discharge were 0.63 (3-Classes Discrete Markov); 0.78 (5-Classes Discrete Markov); and 0.68 (ARIMA (1,0,0)(1,0,1) & ARIMA (0,0,2)(1,0,1)). Optimization simulations were carried out for 16 scenarios with combinations of four discharge models and four guideline trajectories during the 2016-2020 period. Based on the research, the scenario by the 5-Classes Discrete Markov discharge model and the R10 continuous guideline trajectory is the most optimal management of the Cirata Reservoir, with a correlation coefficient between the trajectory was 0.91.

Unreliable power in Malawi mainly results from fluctuating water levels in most run-of-river hydropower plants. These power outages worsen during the dry season making it difficult to accommodate the existing demand of electricity. The best solution to ensure reliability of the hydropower system is to incorporate reservoir storage. This study aimed at designing a reservoir based hydropower system to ensure reliability and maximum generation of power at a low cost. The system was designed to export all the energy to national grid for distribution. The monthly average design flow was 29.129 m3/s. Reservoir storage capacity of 536.998 Mm3 was estimated using mass flow curve in MS-Excel while potential head of 100 m was deduced using Google Earth. RETScreen software was used to calculate hydropower potential and determine financial viability of the project. The results showed that the hydropower potential was 22.70 MW and the initial capital cost was $79,434,044 with payback period of 4.8 years. This paper’s levelised cost of energy (LCoE) was 0.099 $/kWh which relatively smaller than grid cost of 0.155 $/kWh. Therefore, this paper presents part of the solution for the persistent power outages and also overcomes the serious power problems during dry season in Malawi.
