“…Geomorphic analysis suggests that the Indus River has had a very dynamic regime in the past [12,13]. Water regulatory bodies must consider designing hydraulic structures to cope with more severe natural catastrophic challenges expected to occur [14][15][16]. Barrages and weirs are engineered structures designed to redirect water flow from rivers to serve multiple purposes such as irrigation, navigation, power generation, and supplying water for drinking and industrial use [17,18].…”

As vital hydraulic infrastructure, barrages and canals are crucial for agricultural irrigation in Sindh Province, Pakistan. Any deviation from the intended design discharge can significantly impact water resource management, leading to economic losses. The Ghotki Canal in Sindh faced challenges in receiving its allocated inflow, prompting an extension of the divide wall at Guddu Barrage to 589.59 ft. However, this extension inadvertently exacerbated the problem by reducing the Ghotki canal's inflow, resulting in a 166.7 ft gap between the original and extended divide wall segments. This study takes a unique approach, using a non-distorted physical model at a scale ratio of 1:85, to assess the influence of the divide wall gap across five scenarios, varying gap width and river flow rates from 100,000 to 500,000 cusecs. The findings highlighted the disruptive effects of the gap on flow regimes, notably affecting critical infrastructure such as the silt excluder and left pocket capacity. Alterations in the divide wall gap width predominantly impact the Ghotki Canal discharge while minimally affecting the Rainee Canal. Without a divide wall gap, the Ghotki Canal's head regulator draws 88% of the designated capacity, while the Rainee Canal consistently receives its total inflow share of 10,000 Cusecs. In conclusion, this study underscores the importance of structure remodeling in barrages for effective water resource management, emphasizing the need for nuanced approaches to optimize canal performance and sustain agricultural livelihoods and regional development.

“…It has been observed that applying multi-satellite processing increased the precision of lake levels [35]. Lake database has been used as a complementary data to in-situ gauges [38]. Moreover, it has the potential to understand lake changes in areas where access to measurements are limited.…”

Lakes play a role as the sentinel of climate change. Surrounded by vast expanses of barren land with limited infrastructure, there is also a lack of knowledge about the dynamics of dryland lakes. The change of lake area can be effectively monitored by remote sensing, and multi-source satellite altimetry datasets provide the possibility to obtain long-term lake water level data. Using the Global Surface Water Monthly Historical dataset and altimetry water level dataset (Hydroweb), we reconstructed a time series of lake water storage changes in Xinjiang, Northwestern China, by establishing the empirical models based on the statistical relationship between the surface area and water level of each lake. We further explored lake response to climate change. The results show that the storage of water at Ayakkum Lake, Aqqikkol Lake and Aksayquin Lake have been undergoing an obvious expanding trend from 2000 to 2020, at a rate of 3.59×108m3/a, 9.43×108m3/a and 0.44×108m3/a, respectively. In the plain and transition zone, Ulungur Lake showed an upward tendency (0.413×108m3/a) in water storage, while Manas Lake and Bosten Lake experienced shrinkage with descending rates of −0.1×108m3/a and −0.86×108m3/a. Temperature changes significantly affect the lake water storage on plateaus, especially those lakes supplied with a large proportion of glacial meltwater. Precipitation is a key factor for changes of lake storage in the plain and transition zones. Meanwhile, extreme weather and man-made factors also play crucial roles. To reduce the risk of flood and drought disasters, rational regulation of water resources is required, and a large-scale integrated catchment management plan can avoid inadvertent trade-offs. This research provides a new perspective for lake water storage inversion, as well as data support for water resources management in arid areas including Xinjiang.
