“…The presence of the Shivalik foothills in the northern and eastern parts of the area contributes to the steeper slopes. These elevated slopes render this particular region susceptible to soil erosion, a concern accentuated by previous studies (Yousuf et al, 2022;Sharma et al, 2023). Due to the rapid runoff from sloped terrain, erosion is more pronounced, and opportunities for groundwater recharge are limited.…”

Watershed prioritization involves assessing various sections within a river basin to determine their requirements for effective land and water resource planning and management. To achieve economic effectiveness and technical efficiency, decisionmakers need to allocate investments optimally to the most critical watersheds. Therefore, the goal of this study is to evaluate the Sub-Watershed Prioritization Tool (SWPT), a user-friendly GIS tool that uses Python programming language, in the Lower Sutlej River Basin for watershed prioritization. The study analyzed morphometric and topo-hydrological factors and was designed to automatically identify watersheds with critical and priority status through geospatial and statistical analysis. The river basin, having an area of 8577 km 2 , was delineated into fourteen watersheds (WS1 to WS14) using the SWAT model. The ALOS PALSAR DEM, ArcGIS10.4 a, and SWPT were utilized to evaluate the morphometric and topo hydrological factors of the delineated watersheds. The priority ranks to the watersheds were assigned as compound parameter value (CPV), which was calculated by weighted sum analysis. Watersheds with the lowest CPV were given the highest priority rating, and vice versa. Based on the results WS9 was assigned the first rank whereas WS5 was assigned the 14 th rank. Hence, WS9 needs immediate attention for the management of land and water resources. A modern tool such as SWPT can replace time-consuming morphometric and topo-hydrological factors for watershed prioritization. It is important to implement appropriate soil and water management measures in the highly prioritized watershed (WS9) through the study. Geospatial technologybased prioritization of watersheds (based on morphometric and topo-hydrological factors) has great potential to support land and water conservation strategies.

“…Validity of the model: The USLE family of models has been globally used to predict soil erosion and sediment yield at the basin scale since the mid-twentieth century and has been the subject of recurrent validations over time. In fact, the USLE was used by the Regional Government of Andalusia to estimate those soil erodibility and cover management factors that were used for the calculations provided in this work, and the M-USLE is being used recently to predict potential sediment yield in other Mediterranean watersheds (Gwapedza et al, 2020;Berteni et al, 2021;Yousuf et al, 2022;among others).…”

This paper discusses how the beaches of Marbella, on the southwestern Mediterranean coast of Spain, may no longer stay in their natural resilience envelope due to a critically delicate natural sediment transport balance and a degree of artificialization that has entered the whole sedimentary system into a new resilience state. The combination of vigorous terrain and millenary human action and disruptions across and alongshore on the coastline have increased stress on sediment availability. Although sediment circulation in the coastal cell has often been studied, the investigation of the connection between soil loss and river sediment transport and retention at a major dam remains a challenge. In this article, a first-order sediment yield prediction was established by using a GIS-based model applied to the area’s main river basin, and validation of model results is provided by empirical measurements of sedimentation in the main reservoir lake of La Concepción using Differential Global Positioning System (D_GPS)/Echo-sounder combination and measurements from remotely piloted aircraft compared with preconstruction blueprint topography documenting spot heights where sediments accumulated or eroded over 50 years. The marine circulation is interpreted from previous research by the authors that established a source-sink pattern similar to the Atlantic platform-fed marine system that originated the significant Cabopino dunes. The significant erodibility that we have estimated seems matched by potentially high sediment accumulation rates along selected profiles and spot heights across the bottom of the reservoir lake, and, in combination with the marine circulation model, our results identify that sediment budget key elements in Mediterranean settings, such as soil loss, sediment entrapment in reservoirs, and the coastal marine circulation, are in a state of deficit that suggests that the resilience envelope is surpassed and the system as a whole is entering a new resilience state in which the engineering factor is key. Some ecosystem services, such as the protection offered by the natural resilience of the beach and dune system of Cabopino, are no longer recoverable in the current artificialization state of the system as a whole.
