The gap

Evidence profile

Sourced from the stated research gap and stated challenges and future-work section of the source papers, classified as general, drawn from work published between 1982 and 2026, spanning 5 journals.

Supporting evidence — 6 representative gaps

• Rainfall, floods and river channel changes in the upper Hunter (1982) · Australian Geographical Studies · doi

  The study identifies a gap in understanding the relationship between rainfall, floods, and river channel changes. The findings highlight the need for further research into the impacts of climate change on river systems.

• Assessment of Urbanisation Extent and Its Influence on Stormwater Runoff in Kigali City (2026) · East African Journal of Environment and Natural Resources · doi

  There is a need for a spatial evaluation of the link between urban development and stormwater dynamics. The study identifies a gap in understanding the influence of urbanisation on stormwater runoff in Kigali City.

• Hydrological modelling in a data-scarce semi-arid catchment: Assessing urbanisation impacts on runoff in Bouskoura, Morocco (2026) · Journal of Water and Land Development · doi

  Limited research has provided quantitative, model-based assessments of recent land-use dynamics and their hydrological consequences in the Bouskoura catchment. The absence of observed streamflow data prevents calibration and validation of hydrological models in the region.

• Drivers of flash flood frequency and intensity in the United States: a quantitative analysis of hydrometeorological interactions (2026) · Natural hazards and earth system sciences · doi

  Inconsistent changes in precipitation and flooding. Limited quantitative understanding of interactions between precipitation, temperature, and land cover in streamflow dynamics. Challenges in obtaining complete year-round hourly instantaneous streamflow records.

• Examination of hydro climatic trend and drought analysis for climate resilience in the eastern escarpment of Abaya Chamo sub-basin, Rift Valley Lake Basin, Ethiopia (2026) · PLoS ONE · doi

  Climate change has adverse impacts on socioeconomic development. The severity of climate change effects varies across countries and hydrological catchments. There is a need for comprehensive integrated hydroclimatic analyses.

• Hydrological modelling in a data-scarce semi-arid catchment: Assessing urbanisation impacts on runoff in Bouskoura, Morocco (2026) · Journal of Water and Land Development · doi

  Further research is needed to calibrate and validate hydrological models using observed streamflow data. The study's findings can be used to inform urban planning and development strategies in semi-arid regions. Future research should consider the complexities of land-use evolution and the impact of climate variability on hydrological processes.
