Publications

Main research fields:
  • Analysis and modeling of surface runoff with special focus on the spatial and temporal distribution of soil moisture

    Research grants and funded projects:
  • TÁMOP 4.2.2 C/“SROP-4.2.2.C-11/1/KONV-2012-0005” Scholarship (Well-being in the Information Society); Improvement of flow estimation methodologies for small catchments in SW Hungary (participant)
  • Environmental impacts of atmospheric precipitation formation; TÁMOP-4.2.1/B-10/1-2010-0002, 2010-2014 (participant). The participant/applicant’s task is the establishment of an environmental monitoring system in selected watersheds in SW Hungary. The monitoring network will provide data for a real-time experimental flash flood forecasting/guidance and early warning (FFG) system and constitutes of soil moisture sensors, rain gages, stream gages, leaf wetness sensors, lysimeters and data loggers.
  • Use of GIS data for the complex monitoring of the sewage conduit system of Pécs, 2011-2012; Collaborative research with a local water utility company, Tettye Forrásház, Pécs, total funding: 4M HUF (Co-PI). The applicant’s special task in this project is the establishment of a raingage network and model runs to simulate runoff. The monitoring system constitutes of 9 rain gage providing rainfall data for Pécs. Data is used for the numeric model-based complex analysis of sewage system conveyed water in Pécs.
  • Integrated Approach to Flood Risk Management on small Catchments (INARMA) Central Europe Operational Programme 2007-2013; More information: inarma.eu. Total project budget: 1,061,553 Euro. The Hungarian partner alongside partners from Austria, Italy, Germany and Poland is the South Transdanubian Water Management Directorate. UP served as sub-contractors with the participation of Drs. Ervin Pirkhoffer and Szabolcs Czigány. UP was in charge for the determination of critical risk locations and on-site monitoring system-based complex hydrometeorological characterization of the sub- and tributary catchments of the Bükkösd Stream (SW Hungary). For hydrometeorological characterization the HEC-HMS runoff and the HEC-RAS flood mapping softwares were used. Results indicated a high degree of reproducibility for selected observed bankfull and flood level flow time series for both the trunk and tributary streams when the disastrous May 15 to 18, 2010 events were modelled.
  • Monitoring of soil thickness in small mountainous watersheds based on geoelectric resistance measurements; Baross Gábor Grant, REG-DD-KFI-09/PTE-TM09, 2010-2011(PI, total funding: 40.9 M HUF); The project aimed to (i) elaborate a rapid and simple method for watershed-scale soil and unconsolidated depth technology and (ii) studied the impact of soil depth and soil moisture content on the magnitude of runoff in a 1.7-km2 forested experimental watershed in the Mecsek Hills, Southwest Hungary. Soil depth values were determined with vertical electric sounding (VES)-technique in 50x50 m grids, borehole drilling and dynamic probing. Runoff was then simulated with the HEC-HMS runoff model, while model verification was carried out by observed (measured) flow time series at the outflow points of the pilot catchment.
  • Forecast of the severe thunderstorms and their environmental effects. National Program for Research and Development NKFP3-00022/2005 (OMSZ-VITUKI-UP Collaboration, Co-PIs: Horváth Ákos (Hungarian Meteorological Service), and István Geresdi (UP), participants at UP: Ervin Pirkhoffer és Szabolcs Czigány, 2005-2008, total funding: 50M HUF; The participants at UP shared the responsibilities for the mapping and classification of flash flood vulnerability of watersheds ranging between 10 and 100 km in area in the low-mountain and hilly areas of Hungary based on GIS databases. Watersheds were classified between 1 and 6 according their flash flood hazard level.
  • Determination of threshold precipitation and discharge values for the low-mountain and hilly catchments of Hungary; Environment and Energy Operative Programme, KEOP-2.5.0.B/2009; 2009-2010 (participants on behalf of UP: Ervin Pirkhoffer and Szabolcs Czigány); Fellow was responsible for HEC-HMS rainfall-runoff model runs for selected flash flood-prone watersheds located in Hungary to determine bankfull flow generating threshold precipitation values at various rainfall-intensity scenarios and initial soil moisture contents.
  • Floodrisk mapping, flood hazard survey and methodological elaboration of hazard mapping using GIS tools for the mountainous and hilly areas of Hungary; Environment and Energy Operative Programme, KEOP-2.5.0.B/2008, 2008-2009 (participants: Ervin Pirkhoffer and Szabolcs Czigány); This project aimed to delineate the watersheds of highest flood risk in the low-mountain and hilly areas of Hungary. The participant also contributed to the elaboration of the methodology used for the elaboration of a GIS-based flood hazard map for Hungary.
  • 2007-2011. OTKA K 68903: Landscape geographical evaluation of landscape pattern and land use in the floodplains of Transdanubia, Hungary 6,133M HUF. PI: Dr. Dénes Lóczy; Participant was responsible for the soil textural characterization (particle size distribution and determination of soil physical type) in selected pilot floodplains along the Kapos Stream, SW Hungary.
