“…The study was carried out in Fuente de Piedra lake (36°06′ N, 4°45′ W), a shallow and saline (athalassohaline) lake and associated marshland with an area of 1364 ha. It occupies the center of a topographically endorheic basin with a catchment area of about 150 km 2 in southern Spain, situated between the Guadalquivir watershed and the Guadalhorce watershed (Heredia et al 2010) (see Fig. 1).…”

Monitoring spatio-temporal dynamics of hydrology in seasonally-flooded wetlands is important for water management and biodiversity conservation. Spectral data and derived indices from t he Moderate Resolution Imaging Spectroradiometer (MODIS) have been used for hydrological monitoring of large wetlands. However, comparable studies for small wetlands (<25 km 2) are lacking. Our aims are to examine whether MODIS-derived indices at 500-m spatial resolution can perform this task for small wetlands, and to compare the performance of various indices. First we evaluated if water levels are a good indicator for wetland inundation extent. A high correlation between water level and Landsatderived inundation extent was found (R 2 =0.957). Secondly, we compared 10 years of water level fluctuations with seven spectral indices at a 16-day interval. The Tasseled Cap brightness index (TCBI) had the highest correlation with water level for the complete time series including dry and wet years. Thirdly, we analyzed how these indices behave for areas with different inundation characteristics. Again TCBI showed a consistently accurate performance, which was independent of inundation frequency. We therefore conclude that TCBI is the best-suited index for monitoring of hydrological variability in small seasonally-flooded wetlands such as the Fuente de Piedra lake in southern Spain. We recommend testing this index further for other seasonally-flooded wetlands in semiarid areas.

“…The study was carried out in Fuente de Piedra lake (36º06' N, 4º45' W), a shallow and saline (athalassohaline) lake and associated marshland with an area of 1,364 hectares. It occupies the center of a topographically endorheic basin with a catchment area of about 150 km 2 in southern Spain, situated between the Guadalquivir watershed and the Guadalhorce watershed (Heredia et al 2010) (see Figure 2.1). The study site is one of the most important breeding sites for the Greater Flamingo (Phoenicopterus roseus) in the Mediterranean region, second only to the Camargue, France (Geraci et al 2012).…”

PhD journey is truly a marathon event full of challenges. Alongside the challenges, there is also the joy of the journey itself and the many inspiring people encountered along the way. I would like to thank everyone who was involved in this journey. First and foremost, I would like to express my sincere thanks to my promoter, Prof. dr. Andrew K. Skidmore, who provided me the opportunity to undertake this PhD research at ITC and led me to the scientific world in the first place. It has been an honour to be his PhD student. He always encouraged me to keep learning new things and seeking answers to "why". He has taught me, both consciously and unconsciously, how to think critically and defend my views, and how to work smarter instead of harder. I am very grateful for his continuous guidance and support. This thesis would not have been possible without the support and guidance of my daily supervisor A/Prof. dr. Anton Vrieling. I am so lucky to have him as my supervisor for this PhD research. During all these years, he guided me with infinite patience and full support, providing useful discussions, constructive criticisms, enlightened ideas, and excellent English editing. He was always the first person helping me out whenever I got in the coming years (Prigent et al. 2012; Vörösmarty et al. 2000). Natural factors affecting water bodies include anomalous high-rainfall-driven flood events (Cian et al. 2018), drought events due to rainfall deficits (van Dijk et al. 2013), seasonal thawing and snowmelt in spring (Watts et al. 2012), and longer-term environmental changes (Lutz et al. 2014; Street and Grove 1976). Many human activities directly affect the availability of water resources. Examples are groundwater pumping, drainage of wetlands, irrigation schemes, and construction of new dams. Anthropogenic changes in land surfaces such as urbanization, agriculture and deforestation also lead to changes in surface water. These changes strongly affect ecosystem functioning, which further results in shifting species distributions and composition (Koning 2005; Robledano et al. 2010), especially for species that are sensitive to hydroperiod variability (Baldwin et al. 2006; Roshier et al. 2002). It may also affect other ecosystem functions including ground water recharge and nutrient cycling (Leibowitz 2003). Globally, the biodiversity of water-related ecosystems continues to decline at an alarming rate (Collen et al. 2014). In addition to these direct threats, the changes of surface water further influence climate change (Degu
