“…A number of studies considered the ecological effects, especially on benthic communities, of the inflow of geothermal waters. Most of these studies (e.g., Clements et al, 2011) deal with natural phenomena, but a few (e.g., Resh et al, 1984;Fendick et al, 1989; Barbaro and Feola, 1994;Boothroyd, 2009;Snorrason et al, 2011;Helgason, 2017) investigated the effects of effluents from geothermal power plants, or made inferences on the possible impact of geothermal energy development.…”

Biomonitoring is a widely employed approach to track changes in the environment. Its use to assess the impact of geothermal energy exploitation for power production is comparatively minor, and largely referred to Tuscany, Italy, geothermal fields. Most examples describe impacts on vegetation, particularly lichens. Biomonitoring proved useful as a tool to reveal the distribution of specific contaminants (e.g., mercury and H2S), and as an overall indicator of the impact on ecosystems. In consideration of the comparatively low cost/benefit ratio, the use of biomonitoring should be encouraged. In particular, it could prove useful to establish the natural background prior to development of geothermal exploitation, and to document any subsequent change.

“…Successful environmental flow assessments require an accurate understanding of the relationships between flow events and biotic responses (Poff et al, 2009). Studies have established various empirical relationships between ecosystem biomass, communities, and biodiversity, and longterm average river discharges (Arthington et al, 2010;Pasztalenieca and Poniewozik, 2010;Clements et al, 2011). Powell et al (2002) described a series of relationships between historic monthly inflow, and various fish species catch, which were utilized in the TxEMP model to arrive at an optimized inflow-harvest relationship.…”

Abstract. We developed an approach to assess environmental flows in estuaries related to preference of phytoplankton considering the complex relationship between hydrological modification and biomass in ecosystems. As a first step, a relationship was established between biomass requirements for organisms of primary and higher nutritional levels based on the principle of nutritional energy flow of ecosystem. Then, diagnostic pigments were employed to represent phytoplankton community biomass, which indicated competition between two groups of phytoplankton in the biochemistry process. Considering empirical relationships between diagnostic pigments and critical environmental factors, responses of biomass to river discharges were established based on a convection–diffusion model by simulating distributions of critical environmental factors under action of river discharges and tide currents. Consequently, environmental flows could be recommended for different requirements of fish biomass. In the case study in the Yellow River estuary, May and October were identified as critical months for fish reproduction and growth during dry years. Artificial hydrological regulation strategies should carefully consider the temporal variations of natural flow regime, especially for a high-amplitude flood pulse, which may cause negative effects on phytoplankton groups and higher organism biomass.

Abstract. An approach to assess estuarine environmental flow based on phytoplankton preference, including the complex relationships between hydrological modifications and ecosystem biomass, was developed in this study. We initially established a relationship between biomass requirements for primary and higher nutritional level organisms based on the ecosystem nutritional energy flow principles. Subsequently, diagnostic pigments were employed to represent phytoplankton community biomass, which indicated competition between two groups of phytoplankton in the biochemistry process. Considering empirical relationships between diagnostic pigments and critical environmental factors, biomass responses to river discharge were established by simulating distributions of critical environmental factors under action of river discharges and tide currents. Consequently, environmental flows were recommended for different fish biomass requirements. We used the Yellow River estuary as a case study; and May and June were identified as critical months for maintaining environmental flow. Temporal variation in natural river flow dynamics, which was used as a proxy for environmental flow, should be carefully examined in artificial hydrological regulation strategies, particularly during highamplitude flood pulses, which might result in negative effects on phytoplankton groups, and subsequently higher aquatic species biomass.
