Evaluating the effects of different land uses on evaporation and stream flow: A study across 200 catchments in the United States

Studying the effects of different land uses on evaporation and stream flow is a hot and frontier topic in global hydrological research. The occurrence and development of flood disasters are restricted and affected by many factors such as meteorology, hydrology, underlying surfaces and human activities. In recent decades, the changes of...

Spatiotemporal snow pattern in the Qilian Mountains from 2001 to 2018

In many parts of the world, water retained in snowpack and glaciers are critical to the stability of downstream ecosystems and human society. This study sets out to quantify, map, and explain the spatiotemporal pattern of annual snow cover duration, which are quantified by regional differences in the number of annual snow cover days (Dsc) and...

Adsorption of organic micro pollutants with high silica zeolite in secondary wastewater effluent: Competition between OMP and NOM

This work investigated which NOM fraction from secondary wastewater effluent were causing competition with metoprolol and clarithromycin for adsorption site on high silica zeolites (HSZ). This thesis works with five commercially available HSZ frameworks (FAU, MOR, BEA, MFI and FER). Adsorption batch test were performed with demi water,...

Assessing and modeling the hydrological performance of DIT sewers: A case study at Kuiperstraat and H.A.J.M. Schaepmanstraat, Gouda, Netherlands

Gouda deals with land subsidence and groundwater problems. A solution to these challenges is the application of Drainage-Infiltration-Transport (DIT) sewers, on which research is lacking. This thesis provides provides infiltration and drainage capacity values on DIT sewers and helps to understand the governing processes.

The challenge of parameter uncertainty: Finding parameter distributions from hydrological field data for conceptual rainfall-runoff models

Conceptual hydrological model parameters represent characteristics of a catchment. They are an integration of spatial heterogeneous parts of the system. Finding adequate parameter values based on field observations, which represents the heterogeneity of a catchment on the spatial resolution and scale of the model, is considered challenging since...

Monitoring land restoration projects of Justdiggit in Kenya, using downscaled passive microwave remote sensing products of VanderSat

The growing world population and climate change have resulted in increasing stress on the Earth’s ecosystems. Especially the overexploitation of agricultural land, overgrazing and extreme droughts have resulted in land degradation, often called desertification. This leads to the disappearing of natural vegetation, the loss of soil quality, lower...

Reducing the flash flood hazard in the Sinai

In 2010 a large flash flood hit El Arish City, killing at least 6 people and causing a lot of damage. This was not the first time the Sinai was affected by these flash floods, more than 40 flash floods have been recorded in the El Arish watershed in the last 100 years. The...
