In the context of growing demand, loss of quality, increasing regional scarcity, and global climate uncertainty, sustainable water management, as well as more integrated approaches to water planning, are crucial. This is receiving increasing attention through cross-cutting synergetic cooperation between hydrologists and other disciplines. International agencies such as UNESCO are promoters of this dialogue. UNESCO HELP is a cross-cutting programme aiming to improve the links between hydrology and the water needs for society. Complimentarily, the UNESCO Ecohydrology Programme aims to use knowledge about the integrated relations between hydrologic and biologic processes. The Guadiana River, on Portugal and Spain, is a UNESCO HELP basin, and in July 2009, an international HELP forum brought to the Guadiana experts from all continents to discuss, with the planning team and local community, experiences from river basins around the world. More opportunities for cooperation in the Guadiana basin were created with the additional classification of the basin as a Ecohydrology Reference Basin, in 2010. This paper discusses how this particular synergy can be beneficial to the planning process. Under the European Water Framework Directive, river basin plans must integrate ecological, social and economic dimensions. This challenge has proven to be more difficult than expected for European countries. Programs such as HELP and Ecohydrology can effectively support the planning process by improving dialogue between different disciplines, sectors and perspectives on water, resulting in a much richer consideration of the issues and possible solutions. The paper intends to stress the benefits that can be obtained through synergies between UNESCO programs operating within the same river basin.

The Upper Rio Chagres drains 414 km2 of steep, mountainous terrain in central Panama. A tropical air mass thunderstorm on 10 July 2007 produced a flood across the basin that peaked at 720 m3 s−1 at a headwaters gage draining 17.5 km2 and 1710 m3 s−1 at a downstream gage draining 414 km2. The storm also triggered numerous landslides in the upper basin, which facilitated

An Ecosystem Report on the Panama Canal: Monitoring the Status of the Forest Communities and the Watershed2002 •
In 1996, the Smithsonian Tropical Research Institute and the Republic of Panama's Environmental Authority, with support fromthe United States Agency for International Development, undertook a comprehensive program to monitor the ecosystem of the Panama Canal watershed. The goals were to establish baselineindicators for the integrity of forest communities and rivers. Based on satellite image classification and ground surveys, the2790 km2 watershed had 1570 km2 of forest in 1997, 1080 km2 of which was in national parks and nature monuments. Most of the 490 km2 of forest not currently in protected areas lies along the west bank of the Canal, and its managementstatus after the year 2000 turnover of the Canal from the U.S. to Panama remains uncertain. In forest plots designed to monitorforest diversity and change, a total of 963 woody plant specieswere identified and mapped. We estimate there are a total of 850–1000 woody species in forests of the Canal corridor. Forestsof the wetter upper reaches of the watershed are distinct in species composition from the Canal corridor, and have considerably higher diversity and many unknown species. Theseremote areas are extensively forested, poorly explored, and harbor an estimated 1400–2200 woody species. Vertebrate monitoring programs were also initiated, focusing on species threatened by hunting and forest fragmentation. Large mammals are heavily hunted in most forests of Canal corridor, and therewas clear evidence that mammal density is greatly reduced in hunted areas and that this affects seed predation and dispersal. The human population of the watershed was 113 000 in 1990, and grew by nearly 4% per year from 1980 to 1990. Much of this growth was in a small region of the watershed on the outskirts of Panama City, but even rural areas, including villages near and within national parks, grew by 2% per year. There is no sewage treatment in the watershed, and many towns have no trashcollection, thus streams near large towns are heavily polluted. Analyses of sediment loads in rivers throughout the watershed did not indicate that erosion has been increasing as a result ofdeforestation, rather, erosion seems to be driven largely by total rainfall and heavy rainfall events that cause landslides.Still, models suggest that large-scale deforestation would increase landslide frequency, and failure to detect increases inerosion could be due to the gradual deforestation rate and the short time period over which data are available. A study of runoff showed deforestation increased the amount of water fromrainfall that passed directly into streams. As a result, dry season flow was reduced in a deforested catchment relative to aforested one. Currently, the Panama Canal watershed has extensive forest areasand streams relatively unaffected by humans. But impacts of hunting and pollution near towns are clear, and the burgeoningpopulation will exacerbate these impacts in the next few decades.Changes in policies regarding forest protection and pollution control are necessary.

Overland flow generation in two lithologically distinct rainforest catchments2004 •
Streams on uniformly rainforest-covered, but lithologically very diverse Barro Colorado Island in central Panamá show remarkable differences in their runoff response to rainfall. This lithological diversity is reflected in equally diverse soilscapes, and our objective was to test the hypothesis that contrasting runoff responses derive from soilscape features that control the generation of overland flow. We determined the soil saturated hydraulic conductivity (Ks) of two neighboring, but hydrologically contrasting catchments (Lutz Creek with a flashy and Conrad Trail with a delayed response to rainfall), and quantified the spatial and temporal frequency of overland flow occurrence. The median Ks values at a depth of 12.5 cm are large enough to rule out Hortonian overland flow, but a marked decrease in Ks in Lutz Creek catchment at 30 cm suggests the formation of a perched water table and the generation saturation overland flow; the decrease in Ks in the Conrad Trail catchment is more gradual, and a perched water table is expected to form only at depths below 50 cm. In Lutz Creek, overland flow was generated frequently in time and space and regardless of topographic position, including near the interfluve, with very low thresholds of storm magnitude, duration, intensity and antecedent wetness, whereas in Conrad Trail, overland flow was generated much less frequently and then only locally. We conclude that soilscape features and microtopography are important controls of overland flow generation in these catchments. Our results contribute to the growing evidence that overland flow and forests are not a priori a contradiction in terms.
