Experiments were conducted on level borders of lengths 30m, 60m, and 90m with constant width of 8 m and stream sizes of 1l/s/m, 2l/s/m, and 3l/s/m under three different soil surface conditions, fresh tilth, post irrigation, and maize crop, to determine application efficiency, coefficient of uniformity (CU) and distribution uniformity (DU). Infiltration, depth of water applied, advance and recession times, as well as moisture content data were collected. The depth of water infiltrated during irrigation event was better predicted by a modified Kostiakov equation than Kostiakov's equation as compared to observed values on clay loam soil. The smaller stream size (1l/s/m) took two to three fold more time to reach the lower end of a border length of 90 m in contrast to stream sizes of 2l/s/m and 3l/s/m. However, the difference in advance times between crop and post irrigation surface condition was minimum compared to fresh tilth soil surface condition. The study revealed that the application efficiency, DU and CU increased as stream size increased and decreased with border lengths. The overall application efficiency ranged from 93.98% to 96.76%, while DU and CU ranged from 93.19% to 99.58% and 95.26% to 99.69%, respectively. After irrigation, with crop conditions, there were no significant differences in application efficiencies, DU and CU. In general, there were significant differences (5% probability level) in application efficiencies, DU and CU among border lengths and stream sizes for three soil surface conditions.

Globally, the frequency, regularity, and severity of floods are all increasing due to climate change, and climate change's effects on developing nations are significant. In 2022, the worst floods in Pakistan's recorded history occurred. One-fifth of the nation experienced significant destruction, which led to significant economic losses and fatalities. However, the resilience of the local population to withstand the effects of calamities has not received enough attention in rural villages along the Indus River. This descriptive cross-sectional research examined how three communities in high-risk locations in Khipro, Sanghar District, Sindh, Pakistan, perceived and responded to flood dangers based on their past experiences. A survey was conducted with a total of 50 individuals in three villages. To measure flood risk perception, three variables—awareness of floods, concerns about floods, and preparedness—were used. Descriptive statistics, the chi-square test, and Pearson's correlation were applied to find correlations and differences across variables. The study adds valuable knowledge about how people perceive the risk of flooding and how factors like age, education, differences in monthly income levels, low-risk awareness, and preparedness influence that perception in rural areas. This study's findings can be used to evaluate flood risks and adopt local adaptation strategies in flood prone areas.
