“…The model emphasizes the description of how water management is based on the interaction between variables in the water balance with the development of the Magetan Regency area (Simonovic, 2002;Tianhong, Songnan and Mingxin, 2019;Maswanganye et al, 2022;Salehi, 2022). The main stages of designing a water management model using the system dynamic method sequentially are (Sterman, 2000):…”

“…The availability of lake water in Magetan Regency refers to three large (main) lakes, namely the Gonggang Poncol Reservoir, Sarangan Lake, and Wahyu Lake. Surface water is mainly used for agricultural irrigation needs in Magetan Regency (Halli et al, 2022;Maswanganye et al, 2022;Jayanti et al, 2023).…”

“…The area of irrigated rice fields in Magetan Regency is equivalent to 40.6% of the area of Magetan Regency. The irrigation water needs of the agricultural sector and the water needs for river maintenance depend on the availability of rivers and lakes (Halli et al, 2022;Maswanganye et al, 2022).…”

“…The surface water balance shows a surplus because it is supported by the volume of water reserves in lakes/reservoirs. Even so, the amount of water reserves in the lake/reservoir will be exhausted if there is no inflow of water; either from the hydrologic cycle from rainwater, or from river water discharge (Maswanganye et al, 2022).…”

“…Integrated water management is needed to avoid critical water conditions in Magetan Regency in the future. The design of a water management model based on regional development in Magetan Regency uses the system dynamic method (Simonovic, 2002;Pedro-Monzonis et al, 2015;Tianhong, Songnan and Mingxin, 2019;Ahmad et al, 2021;Maswanganye et al, 2022;Motschmann et al, 2022;Salehi, 2022;Bhunia, Shit and Brahma, 2023). The first step is to validate the model.…”

Background. The need for water in Magetan Regency, Indonesia, continues to increase along with regional development. Objective. To identify the condition of the water balance and water critical index in Magetan Regency; and forming a regional development-based water management model in Magetan Regency. Methodology. Formation of a water management model based on regional development, both demographically and regional economic development (agriculture, livestock, fisheries, industry, and tourism), and the environment (river and lake maintenance). This study uses water availability data from seven watersheds. The water management model uses a dynamic system model, with an analysis coverage throughout the Magetan Regency area. The annual water balance of Magetan Regency shows that the water balance and water critical index of Magetan Regency are in near critical condition. Integrated water management is needed to avoid critical water conditions in Magetan Regency in the future. Results. Based on the results of model simulations with the application of policy simulations, the water balance in Magetan Regency during the period 2016 to 2030 is still in a near critical condition, but critical water conditions only occur during the 2018-2020 period. Implications. Critical water conditions in the future can be avoided by implementing policy scenarios. The policy scenarios include: (1) reforestation, planting 500,000 tree seedlings each year, (2) maintenance of rivers and lakes twice a year, (3) construction of a reservoir with a capacity of 5000 m3 each year. However, water availability is still fluctuating because the main factor for water availability is rainfall. Conclusion. the policy scenario is proven to be able to increase the availability of water in Magetan Regency.

The problem of water supply in arid regions is still topical and needs to be studied. The aim of the study was to develop a program for the analysis of the dynamics of water resources from the satellite images of the Saratov region. The analysis of the images made it possible to create a program for calculation of the water surface area of the water bodies used for estimation of the water reserves dynamics depending on climatic and anthropogenic factors from 2007 to 2022. The water bodies located in the most arid area of the arid region of Saratov region and used by the population for household and drinking water supply were investigated in the work. The results showed a direct marked relationship between the volumes of spring water supply and precipitation. Also revealed a direct high correlation between the reduction of water reserves in summer and the volume of precipitation from May to August. The program and revealed regularities can be used for estimation of water reserves in artificial lakes and rivers of arid regions.
