A Physics-Based approach for Rating Curves to Reduce Uncertainties: A New Concept for Hydrological Model Calibration

The direct measurement of discharges in rivers can be time-consuming and costly. The discharge is commonly estimated indirectly by means of a curve, relating water level to discharge. This so-called rating curve is traditionally determined by fitting a curve to a number of observations, which induces several uncertainties and difficulties: 1)...

Measuring coastal erosion with the help of the local population in Myanmar

Coastal erosion in Myanmar causes the coastline to retreat, which increases the flood risk for those who live near the coast. Lack of data about the coastline retreat makes it difficult to design proper flood protection measurements (UNFCC 2007). Since Myanmar is a relative poor country traditional measuring techniques, such as laser mapping,...

An experiment on low-cost RTK GNSS with short baseline performance

This report first elaborates on an experiment to evaluate the performance of single frequency base station performance along with baseline. The system is deployed on a single frequency base station, and low-cost antenna in both and base and rover setup. The experiment is based on taking measurements on six control points, which are selected by...

Genetic Programming in Hydrology: Using genetic programming in conceptual modelling

This report introduces the use of Genetic Programming (GP) into hydrology by describing the results of GP using conceptual hydrological models as physical representation. First the possibilities of GP are tested on synthetic data, which results in a shortlist of good working objective functions and insight in the most important GP settings. The...
