This study aims at improving the hydrological process understanding of the semi-arid and transboundary Incomati river basin to enable better water management. Comprehensive statistical and trend analysis of rainfall and streamflow were conducted, and the Indicators of Hydrological Alteration tool was deployed to describe the streamflow regime and trends over time. Land use and land cover change, particularly the conversion of natural vegetation into forest plantation, the expansion of irrigated agriculture and the flow regulation due to dam operation were identified as critical drivers of flow regime alteration. Hydrograph separation using long-term hydrochemical data at seasonal scale, and hydrochemical and isotope data at event scale were performed to quantify runoff components. A novel methodology to calibrate recursive digital filters using routinely collected water quality data was developed and tested in the catchment. This method allows for estimation of daily baseflow from readily available daily streamflow data. Dominant runoff generation zones were mapped using the Height Above Nearest Drainage approach. The hydrological model STREAM was then employed, informed by the runoff generation zones mapping and the process understanding gained in the catchment, as well as remote sensing data. The study provides the basis for better operational water management in the catchment.

本研究旨在改善對半乾旱及跨界的因科馬提河流域水文過程的理解，以促進更好的水資源管理。進行了降雨量和流量的綜合統計及趨勢分析，並使用水文變化指標工具來描述流量的模式及其隨時間的變化。土地使用和土地覆蓋變化，特別是自然植被轉變為森林種植、灌溉農業的擴展以及由於水壩運作造成的流量調節，被確定為流量模式變化的關鍵驅動因素。利用長期水文化學數據進行季節性水文圖分離，並在事件尺度上使用水文化學和同位素數據來量化徑流組成。開發並測試了一種新方法，利用常規收集的水質數據來校準遞歸數位濾波器。此方法允許從隨手可得的每日流量數據中估算每日基流。使用「距離最近排水高度」方法繪製了主要徑流生成區域的地圖。然後，使用水文模型STREAM，根據徑流生成區域的地圖及在流域中獲得的過程理解，以及遙感數據進行分析。本研究為流域內更好的操作性水資源管理提供了基礎。
作者簡介
Aline Maraci Lopes Saraiva Okello is currently a Post-Doctoral researcher at the University of Zululand, South Africa. Her research interests include hydrology, water resources management, rainwater harvesting, environmental flows, hydrological modelling, remote sensing and open source data. Aline graduated with distinction from the MSc Programme in Water Science and Engineering, specialisation Hydrology and Water Resources, from IHE Delft Institute for Water Education (former UNESCO-IHE), Delft, The Netherlands, in April 2010. Her PhD research was carried out under the RISKOMAN project (Risk-based operational water management on the Incomati River Basin).
Aline holds a BSc Honours degree (Licenciatura) in Civil and Transport Engineering from ISUTC, Maputo, Mozambique. She has been a teacher, researcher and consultant over the past 10 years. She is member of IAHS (International Association of Hydrological Sciences) and WISA (Water Institute of Southern Africa.
She received the L'Oreal-UNESCO For Women in Science Sub-Saharan Africa Fellowship Award in 2013 and the Faculty for the Future Fellowship in 2014 and 2015. She was shortlisted for the Africa Prize for Engineering Innovation 2016/2017 for the development of the mobile application HarvestRainWater. Aline was also selected for the first cohort of the UNLEASH Global Innovation Lab for the SDGs in Denmark, August 2017. In general, she is very interested in research and development, and women & youth empowerment.
