“…Increasing the storage capacity of suitable reservoirs may be a realistic alternative since total inflow will be available [35]. Balancing ecological and socio-economic water use will optimize the functionality of the reservoir [36]. Simplifying the development model by utilizing existing materials in the building environment can be a fairly efficient solution [37].…”

Padjadjaran University built the Leuwi Padjadjaran II Reservoir as a water harvesting facility and conservation area in the Cikeruh Sub-watershed area. This reservoir serves as a water reservoir before being channelled to other river branches and can be utilized as a water reserve collector. The water supply and the degree of water demand in the residential, non-domestic, agricultural, fishery, animal, and industrial sectors are impacted by land use changes and climate changes. This study aims to ascertain the state of the water balance in the Leuwi Padjadjaran II Catchment Area to know the deficit condition and calculate the reservoir serve. F.J. Mock Method was used to examine water availability based on climatology data. SNI 6728.1-2015, PUPR Minister Circular Letter (SE PUPR) Number 7 of 2018, and associated studies were used to analyze water demand. The findings revealed that total water demand was 133.506,09 m 3 /year with an average of 11.125,5 m 3 /month, and total water supply was 138.732,90 m 3 /year with an average of 11.561,08 m 3 /month. Throughout January-May and November-December, the water balance in the Leuwi Padjadjaran II Catchment Area was in surplus. Deficient water balance conditions occur from June-October, requiring water supply. Leuwi Padjadjaran II Catchment Area has a surplus of water, so it is sufficient to be utilized. Still, it is not evenly distributed, so there is a water shortage in several sectors, such as agriculture. To make the Leuwi Padjadjaran II Reservoir useful, conservation measures must be taken to manage the water demand.

Reducing river flows significantly affects livelihoods, ecology and industrial production. Therefore, allowing for ecological flow requirements has been applied to limiting human water consumption and is incorporated into water allocation planning. However, the unavailability of ecological data greatly limits e‐flow studies and this lack of sufficient ecosystem data is mostly addressed by using hydrological metrics as surrogates of the river ecosystem. This study employed the nine indicators of the ‘Flow Health’ model to assess river hydrological health and explore optimal ecological flow regimes. The modelling estimated the required flow and the extra flood flows of ecosystem conservation under default and custom thresholds. Ecological flows were calculated for five stations of the Weihe River through coupling with three hydrological methodologies. The index of flow deviation indicated that the flow regimes in Weihe River have partially changed from the reference period. Fish and other aquatic habitats have changed by reduced flows, but the health of the floodplain ecosystem has not been seriously affected. The ecological flow modelling results showed that the extra flow required for the ecology restoration in five stations is concentrated from July to September. The optimal ecological flows in dry seasons by coupling three hydrological methods were less than the average current flow, which is reasonable. This coupling provides ideas on how environmental flow assessments are undertaken in similar regions.
